본 연구의 목적은 (1) 가정에서의 소비행동을 자원활용적 측면에서 탐색해 봄으로써 소비의 사용/처분 효율성 개념을 제품군 별로 명료화 하고 (2) 사용/처분 효율성과 인구통계적 특성, 환경보전에 대한 태도와의 차이를 실증하기 위한 것이다. 연구대상은 서울시에 거주하는 주부 400명이며, 최종분석에 사용된 자료수는 357부이다. 연구에 따르면 사용/처분 효 율성 개념은 상품군(식품, 의류, 가전제품)에 따라 다르게 규정지어야만 함을 알 수 있었다. 또한 사용/처분 효율성과 몇몇 인구통계적 변수와는 관련이 있음을 보여 주었고, 환경보전 태도는 사용 효율성과 정적관계를 보여 주었으나 처분효율성과는 일과성 있는 관계를 보여주지는 못했다. 이러한 연구결과는 소비자 교육 및 재활용정책에 적극 활용할 수 있으리라고 본다.

The purpose of this research is to distinguish the effect of children's multicultural educational program in the daily life schedule that is integrated in Nuri-programme on children's multicultural acceptance and pro social behavior. Subjects were 4-year-old children from Gyounggi-do A city separated into anexperimental group and acontrol group. Both groups werepre tested. After conducting a program for 44 times, the data was collected using visual resources and instruction considering 4-year-old children's ability to read. In conclusion, the experimental group educated with children's multicultural program showed higher multicultural acceptance. These show that multicultural education affect pro-social behavior.

A hospital-based, matched case-control study was carried out to evaluate the relation ship of various suspected risk factors including snoring and serum level of cholesterol to cerebrovascular disease in Korea. A total of 127 incident cases of cerebrovascular disease(74 cases of cerebral infarction and 53 cases of intracerebral hemorrhage) admitted to. the department of neurology in a university hospital from December, 1993 to March, 1995 were compared with 127 matched controls admitted to same hospital in same period. A multivariate analysis suggested that ECG abnormality(left ventricular hypertrophy and atrial fibrillation), family history of cerebrovascular disease, fundoscopic abnormality, previous history of transient ischemic attack and hypercholesterolemia were risk factors of cerebrovascular disease, ECG abnormality, fundoscopic abnormality, smoking and hypercholesterolemia were also suggested as risk factors of cerebral infarction.

Urinary incontinence (UI), affecting 3%-11% of males and 25%-45% of females globally, is expected to rise with an aging population. It significantly impacts mental health, causing depression, stress, and reduced quality of life. UI can exacerbate psychiatric conditions, affecting treatment compliance and effectiveness. It is categorized into transient and chronic types. Transient UI, often reversible, is caused by factors summarized in the acronym DIAPPERS: Delirium, Infection, Atrophic urethritis/vaginitis, Psychological disorders, Pharmaceuticals, Excess urine output, Restricted mobility, Stool impaction. Chronic UI includes stress, urge, mixed, overflow, functional, and persistent incontinence. Drug-induced UI, a transient form, is frequently seen in psychiatric treatment. Antipsychotics, antidepressants, and other psychiatric medications can cause UI through various mechanisms like affecting bladder muscle tone, altering nerve reflexes, and inducing other conditions like diabetes or epilepsy. Specific drugs like lithium and valproic acid have also been linked to UI, though mechanisms are not always clear. Managing UI in psychiatric patients requires careful monitoring of urinary symptoms and judicious medication management. If a drug is identified as the cause, options include discontinuing, reducing, or adjusting the dosage. In cases where medication continuation is necessary, additional treatments like desmopressin, oxybutynin, trihexyphenidyl, or amitriptyline may be considered.

This study was designed to observe hypoxia-induced mechanical responses of porcine cerebral artery and to clarify their possible mechanisms. Hypoxia produced a transient vasoconstriction, recovering to the basal tension within 10 min and subsequent reoxygenation produced a biphasic (relaxalion-contraction) response in rings with endothelium under resting tension. Hypoxia produced a further contraction in rings precontracted with KCl or $PGF_{2{\alpha}}$, and following reoxygenation caused only sustained relaxation. Removal of the endothelium and pretreatment with nimodipine or indomethacin markedly attenuated the hypoxia- and reoxygenation-induced contractions. The KCl-induced contraction was not affected in hypoxic state, but contractions induced by $PGF_{2{\alpha}}$ or endothelin (ET) were inhibited in the hypoxia, the latter being more sensitive to the hypoxia. Upon reoxygenation, the attenuated contraction rapidly recovered to the original tension. Both hypoxia and reoxygenation significantly increased cyclic GMP content in the intact preparations, but not in the endothelium-removed ones. Acetylcholine (ACh) produced concentration-dependent relaxations in the intact endothelial rings precontracted with $PGF_{2{\alpha}}$ or endothelin, and the ACh-induced relaxation was inhibited by removal of endothelium and by hypoxia. ACh also increased cyclic GMP content in tissues pretreated with $PGF_{2{\alpha}}$ and the increase of cyclic GMP was abolished in hypoxic state. These results suggest that hypoxia- and reoxygenation-induced contractions are dependent on endothelium and extracellular calcium, and related to the release of prostaglandin-like substance(s).

The purpose of this study was carried out to investigate the effect of electroacupuncture on reactive gliosis expressing GFAP in rat with transient global cerebral ischemia. Subjects were randomly divided into two groups, a control group and a electroacupuncture group on ST36, LI11 and SP9 with 2 Hz and 1 mA. The rats were sacrificed on 1, 3 and 7 days after transient cerebral ischemia using ligation of left common carotid artery. After making brain slide sections, they were immunostained with GFAP antisera(1:2,500). The results were as follows: The numbers of astrocytes of electroacupuncture group were decreased than those of control group at every 1, 2 and 7 days. Especially, the numbers of astrocytes at 3 days(p<0.01) and 8 days(p<0.05) were different statistically. And astrocytes had resting, hypertrophic and moving types on cerebral cortex. The decrease of numbers of astrocytes expressing GFAP showed that electroacupuncture could localise and minimize the brain damage by transient cerebral ischemia and cause brain cell plasticity.

Under ubiquitous work environment, innovative changes occur in work process with ICT. The work process for collaboration through mobile devices and network should be investigated. The research model consists of two major antecedents: autonomy and interdependence as a task characteristic and job satisfaction as ultimate consequence followed by work design theory. To elaborate work design theory, smartwork application (app) use, communication extent, and work-life balance were reviewed from the literature. Data were collected from three ICT firms, which adopted certain smartwork app, and a partial least squares analysis was made on 175 data points. The analysis results show that task interdependence exerts a statistically significant effect on the level of smartwork app usage. Communication extent directly affects job satisfaction and work-life balance. The remarkable point is that smartwork app usage does not affect employees' work-life balance; the former can only affect the latter indirectly by increasing communication extent. This study attempts to explain the organizational impact by considering smartwork app and the effects simultaneously. We proposed and empirically tested the extended work design theory including information technology and its environment. Based on the results, other theoretical and practical contributions are discussed at the end with limitations and further studies.

홀스타인 도체를 두쪽으로 나누어 한쪽은 진공포장하여 1$^{\circ}C$에 냉장하고(냉장육), 나머지 한쪽은 함기포장하여 -2$0^{\circ}C$에 동결하였다. (동결육). 두시료의 기호성을 저장 20일, 40일, 및 60일째에 비교하였으며, 비단백태 질소화합물 함량의 상관관계를 검토하였다. 또. 냉장육의 진공포장을 개봉하거나. 동결육을 해동한 후 재냉장한 것에 대해서도 기호성을 비교하였다. 생육향의 경우, 20일과 40일에는 냉장육이 우수하였으나 60일에는 오히려 동결육이 우수하여 진공포장육은 냉장기간이 길어지면서 산소 부족으로 인한 생육향 생성이 적은 현상을 보였다. 두 시료를 재냉장한 후의 생육향도 마찬가지였다. 저장 20일과 40일에현저한 차이는 아니지만 냉장육이 우수한 반면 60일에는 동결육이 우수하였다. 연도는 저장기간에 관계 없이 냉장육이 우수하였고, 해동 후 재냉장에 의해서 향상되었다. 가열육의 기호성은 저장기간에 관계없이 냉장육이 우수하였으며 20일(p<0.01)에 가장 큰 차이를 보였다. 재냉장한 우육의 기호성은 저장 20일(p<0.05)과 40일(p<0.01)의 것은 냉장육이 우수한 반면 60일의 것은 동결육이 우수하였다. 냉장육의 기호성과 비단백태 질소화합물의 상관관계는 유의성이 없었으며, 동결육의 경우 inosin의 유의적인 상관관계(r=0.48)를 보였다.
